I'd be OK with this if "trusted sponsor" meant Bob's Plumbing, and Bob's the second baseman's father who bought the team's uniforms. Sure, let Bob have my email so he can pitch me a tankless water heater. But it's as likely that they're remote conglomerates selling horrible products that damage our kids' health and shorten their lives, like Coca-Cola. And we're handing them a sheaf of vectors to insert their promotional material into our every crevice.
